Esketamine Hydrochloride is employed in clinical settings where NMDA receptor blockade is required for anesthesia and analgesia.

- Induction of anesthesia: Provides rapid onset of dissociative anesthesia for surgical procedures. - Procedural sedation: Enables safe sedation for diagnostic or minor therapeutic interventions. - Analgesia: Offers potent analgesic effect for peri‑operative pain management.

Esketamine may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Dizziness - Nausea - Vomiting - Elevated blood pressure - Headache - Perceptual disturbances (e.g., visual or auditory changes)

Serious or Rare Side Effects: - Respiratory depression - Emergence delirium or severe agitation - Hypertensive crisis - Seizures - Psychotic reactions - Cardiac arrhythmias

Prior to administration, clinicians should consider several safety measures.

- Patient assessment: evaluate cardiovascular and respiratory status before use. - Concurrent CNS depressants: avoid or monitor for additive effects. - History of substance abuse: use with caution and close observation. - Pregnancy and lactation: avoid unless benefits outweigh potential risks. - Monitoring: continuous vital‑sign monitoring during and after administration. - Store at below 25°C: keep in original container, protect from light and moisture.

Esketamine can interact with other medicines, influencing its safety and efficacy.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis. - Other NMDA antagonists: additive central nervous system depression. - Sympathomimetic agents: may exacerbate hypertension.

Moderate Interactions (Monitor Closely): - Benzodiazepines: may reduce anesthetic effect, requiring dose adjustment. - Opioids: increased risk of respiratory depression. - Antihypertensive drugs: may need titration to maintain blood pressure control.
